I have a similar problem... but not with ls.
# md5 biglonguglyfilename.zip
MD5 (biglonguglyfilename.zip) = 511fdc3352d9265ffac0d472de7bb994
# md5 differentbiglonguglyfilename.zip
md5: differentbiglonguglyfilename.zip: Input/output error
These files can be read with no problem in Linux, whether I mount the
system as ext3 or ext2.
I did not create this file system; it was from a 3rd party.
Here is tune2fs output from a Linux machine:
# tune2fs -l /dev/sdb1
